Abstract
A method for transmitting a signal in an optical system includes generating an optical signal along an optical axis for transmission through an optical element, positioning the optical element so that a surface discontinuity is positioned along the optical axis such that the optical signal defines a substantially radially symmetric intensity profile, and launching the optical signal into an input face of an optical fiber such that the intensity profile is substantially null proximate an optical axis associated with the optical fiber.
